Patent CA-2261590-A1 (CA)
Title: Apparatus and method for removing condensable material
Inventor: BARNWELL JAMES W
IPC: B01D5/00
Filed: 1997-04-29
Abstract: An improved method and apparatus are disclosed for removing condensable material from a gas. The gas is caused to flow in series through a chiller for cooling the gas and condensing the condensable material from the gas, then through a separator to separate the condensate from the gas, and then passing the gas through a reheater to reheat the gas. A predetermined charge of refrigerant is passed in a closed cycle through the chiller to cool the gas by absorbing the heat from the gas and evaporating, then the gaseous refrigerant is compressed by a compression unit having an electric drive means in which an amount of energy is added to the gaseous refrigerant. The hot, pressurized, gaseous refrigerant is then passed through an auxiliary condenser sized to remove the energy that was added to the refrigerant by the compression unit at no load conditions, then the refrigerant is passed through the reheater to further condense the refrigerant and to transfer heat to the exiting gas. The refrigerant then exits the reheater and returns to the chiller, completing the closed cycle. The predetermined charge of refrigerant is sized to cause the refrigerant exiting the reheater to be in a substantially gaseous state when there is no flow of gas through the reheater and to cause the pressure of the refrigerant exiting the reheater to generally decrease as the flow of gas through the reheater increases.

Patent CA-2282319-A1 (CA)
Inventor: RICCIARDELLO SALVATORE
IPC: B63B35/34
Filed: 1998-02-17
Abstract: This utility model presents two fundamental features: a) telescopic loading bridge; b) ballast tank mounted on motor crawler tracks. Feature a) enables the adjustment of the landing stage to any type of boats and/or coasters, and the appropriate adjustment of the landing stage's length to any littoral, high tide and to any exceptional conditions which might arise during the normal operating time. The retractility function enables the easy removal of the landing stage from its designated location; Feature b) enables to move the whole structure to safer locations when the original location is exposed to particularly strong surges which might endanger the stability and the normal functioning of the landing stage. Once the exceptional condition has ceased, the motor crawler tracks will enable the landing stage to return to its normal functioning. Said feature therefore reduces the eventual "inactivity" of the landing stage.

Title: Nucleic acid sequences that can be used as primers and probes in the amplification and detection of all subtypes of hiv-1
Inventor: LUKASHOV VLADIMIR VLADIMIROVIC
IPC: C12N15/09
Filed: 1998-08-05
Abstract: The present invention is related to nucleic acid sequences that can be used in the field of virus diagnostics, more specifically the diagnosis of infections with the AIDS causing Human Immuno-deficiency Virus (HIV). With the present invention nucleotide sequences are provided that can be used as primers and probes in the amplification and detection of HIV-1 nucleic acid. The oligonucleotide sequences provided with the present invention are located in the LTR part of the HIV  viral genome. It has been found that, by using the sequences of the present invention in methods for the amplification and detection of nucleic acid a sensitive and specific detection of HIV-1 can be obtained. The benefit of the sequences of the present invention primarily resides in the fact that, with the aid of primers and probes comprising the sequences according to the invention the nucleic acid of all presently known subtypes of HIV-1 can be detected with high accuracy and sensitivity. So far no primer pairs or hybridization probes have been developed that would allow the detection of such a broad range of HIV-1 variants. The oligonucleotide sequences according to the present invention are especially useful in methods for the amplification of nucleic acid.
